I am getting the following error when starting the Exchange 2010 EMC on a SBS 2011 Standard: The following error occurred while attempting to connect to the specified Exchange server 'domain name' The attempt to connect to http://domain.local/PowerShell using 'Kerberos' authentication failed: Connecting to remote server failed with the following error message: The WInRM client cannot process the request.

Verify the unencrypted traffic setting in the service configuration or specify one of the authentication mechanisms supoorted by the server. To use Kerberos, specify the computer name as the remote destination. Alsoverfy that the client computer and the destination computer are joined to a domain.

To add to the above comment, I have checked many configuration and the look all good. Big help is needed. Thank you

Hi Please confirm that whether you have other applications using the same port (80) with Default website . For instance whether you have sharepoint deployed.(SBS will install it) If indeed, try to change the application to use other port and test again.

Hi, Yes it was that I had another application was using port 80. How it got there its a mistery. All i had to do is the stop the application in the IIS and reset the IIS. Now working fine.
